1985 250 FourTrax

My son bought a 1985 Honda 250 FourTrax for cheap, but it needs a new rear brake. I removed the wheel and all the bolts around the outside of the brake cover, but the cover does not come off. Am I missing something? I check the parts assembly manual and it does not look like there should be anything else holding it on. I already chipped one of the flanges pounding on it trying to get it to come loose.
